PI Point(and attribute) not updated by AF analysis

Question asked by Preverco on Apr 16, 2019

Hello,

 

Since we updated our PI systems last month, some attributes that should take value from analysis are having other values (randomly?).

Below, the attribute in blue should be the same as the one in red (or take the value -1). but at some time, it took another value, and we don't know why.

The blue attribute is backed up in a PI Point, but not the red one.

EDIT :

The analysis is triggered every minute.

the C:\ProgramData\OSIsoft\PIAnalysisNotifications\Data\Recalculation\recalculation-log showed this at the same time of the bad value change :
\\*PI Element*\Analyses[*analysisName*];1880ede3-dbba-11e8-a968-005056922136;Automatic Backfilling;NoArchiveData;PI Analysis Service;16-Apr-19 10:01:00--16-Apr-19 10:01:34.609;Completed;16-Apr-19 10:01:41;0;Queued by PI Analysis Service at 16-Apr-19 10:01:34.850.

 

Also the message log shows :
